Struct std::rand::distributions::FisherF
[−]
[src]
pub struct FisherF { numer: ChiSquared, denom: ChiSquared, dof_ratio: f64, }
Unstable (
rand
): use rand
from crates.io
The Fisher F distribution F(m, n)
.
This distribution is equivalent to the ratio of two normalised
chi-squared distributions, that is, F(m,n) = (χ²(m)/m) / (χ²(n)/n)
.
Fields
numer | Unstable ( rand ): use |
denom | Unstable ( rand ): use |
dof_ratio | Unstable ( rand ): use |
Methods
impl FisherF
fn new(m: f64, n: f64) -> FisherF
Unstable (
rand
): use rand
from crates.io
Create a new FisherF
distribution, with the given
parameter. Panics if either m
or n
are not positive.
